Bedroom10 Best King Single Trundle Beds In Australia

Whether they’re for the kids’ rooms or guest bedrooms, king single trundle beds are roomy and functional pieces of furniture that solve the problem of limited space.

A trundle bed is essentially two beds in one. The bottom bed sits very low to the ground and tucks in nice and snug under the main top bed, freeing up space when the spare bed isn’t needed and providing a speedy solution for sleepovers. Called ‘trundles’ because of their handy castor wheels, these genius space savers are guaranteed to get years of use in busy families, and in a king single size, they’ll see the kids right through from toddlerhood to the teenage years.

What is the point of a king single trundle bed?

Dog lies on a trundle bed in a kids room.
Bunkers Trundle Bed
  • They are perfect for growing kids. Singles quickly become a bit too snug for fast-growing kids, but king singles can easily see them right through to the teen years.
  • The spare bed is out of sight. With a trundle that slides right under the main bed, you’re able to keep the floor clear space and the room looking tidy even while houseguests are still around.
  • The trundle doubles as storage space. And no family can ever have too much storage! Instead of storing a mattress, use the space for bedding, toys and linen.
  • You’re all set for sleepovers! Whether it’s cousins or best mates, sooner or later you’ll have little houseguests under your roof. A trundle keeps kids together in the same room but in the comfort of their own beds.
  • They look great! More luxe than a single, but not as imposing as a double, a king single looks just right. Paired with a beautiful quilt cover, bedside tables and a bedroom rug, it’s a room you’ll be happy to invite guests into.

Can adults sleep on trundle beds?

Yes, in most cases, adults can sleep on trundle beds, especially when paired with a quality mattress. King single trundle beds are especially brilliant for adults because of the extra length they offer, which is more than a double bed.

Do trundle beds use regular mattresses?

Yes, trundles usually work with any regular mattresses of your choice. Just be sure to check the size is correct for the bed you’ve chosen.

Can a trundle be added to any bed?

You can only add a trundle to your existing bed if you have enough space underneath for it to fit. Get out your tape measure and check the distance from the base of the bed to the floor, then compare this with the trundles you’re looking at. And if you plan to keep the trundle bed made up for a guest staying a few nights allow some extra space for the bedding.
